Konkona Sen Sharma is unable to sleep at night. Even though she isn't a proper insomniac , Koko has been tossing and turning in bed for the last few months. We thought maybe her marital problems with husband Ranveer Shorey might have kept her awake. But the real culprit is her son Haroon who turns 2 years old this March. At a recent event for her up coming film Ek Thi Daayan, Koko was heard saying, " My son Haroon is giving me sleepless nights! It's not the promotion that is keeping me awake." When asked if she belives in ghost and supernatural powers, she said, "I do believe in it a little."
